File:Grandmaster 579.gif
If one seeks to capture a thief, one should send a thief. For only a thief truly comprehends just what another is and what it takes to vanquish. I am that thief that one sends.
Cassidy Cain

Grandmaster of Theft is an epic which blends elements of Action Adventure, Comedy, Thriller, Crime Fiction, Wuxia, Romance, and Mystery. The stories are broken up into a series of 10 Volumes with each story told through combination of multi-part and solo episodes.

Cassidy Cain is heiress to CAINternational, strategical & tactical prodigy, a martial arts enthusiasts, and one of the world's greatest criminal masterminds. Believing in the motto of "It Takes a Thief to Catch a Thief," she uses the exact same corruption criminals do to get away on them to see to their defeat as the noble thief of justice, Grandmaster of Theft.

Partnered with her personal assistant Augustus Wynn and mentor/grandfather Edan Cain, Cassidy uses her own money, status, connections, social skills, and above all else, intelligence to outwit the corrupt, assist others, evade capture, and hunt down a criminal mastermind known only as Deus.

Wynn: No prob. Only thing I ask to know is why you think that?

Cassidy: Because that's what I'd do.


 Gale: Seeing as you've concluded your business with her, you should not be pressed to conduct some with me now, would you? I've just a couple of questions to ask.

Cassidy: It's an attractive offer, but I've no interest in discussing such matters on top of a train.

And if she lost, as she did, she had the fake one as back-up to be taken by Cassidy then keep the real one with her to use as evidence of her victory.
